This program will process monthly precipitation amounts and user requests.

1.       This program will process arrays of data to provide information to the user.

2.  Create 5 functions

a.  queryUser();

                        i.   prompts the user for an action and then returns an integer based on user choice

·         1 to print all

·         2 to calculate differences and print all

·         3 to see a single month

·         4 or more to quit

b.  processQuery (int query, string month[], double actual[], double average[], intsizeOfArrrays);

                        i.   checks the user query and calls a function based on the query

                       ii.   Use a switch case

·         1 calls printAllArrays

·         2 calls calcAllDifferences

·         3 calls displaySingleMonth

c.  printAllArrays (string month[], double actual[], double average[], intsizeOfArrrays);

                        i.   prints all the data in table form (see sample run)

d.  calcAllDifferences (string month[], double actual[], double average[], intsizeOfArrrays);

                        i.   calculates the monthly difference for each entry:  actual - average

                       ii.   prints all the data in table form including the difference(see sample run)

e.      voiddisplaySingleMonth (string month[], double actual[], double average[]);

                        i.   asks the user for a month to display (1 – 15)

                       ii.   remember these arrays are addressed 0 – 14

                     iii.   calculates the selected month difference

                       iv.   prints the data in a single line form including the difference(see sample run)

3.  the main function will

a.       Create 3 arrays…use the data from the chart below

                                                               i.      Month will hold the month as a string

                                                             ii.      Actual Rainfall will hold actual rainfall

                                                            iii.      Average Rainfallwill hold actual rainfall

b.      Calculate the size ( as shown in class) of the Actual Rainfall Array

c.       Set the cout precision and fixed decimal

d.      Welcome the user

e.      Call queryUser

f.        while loop as long as the user choice is a 1, 2, or 3

                                                               i.      Call processQuery

                                                             ii.      Call queryUser

 

g.  Thank the user for their business
